Nitrendipine in hypertension that is difficult to control

Area of Science:

• Cardiology
• Pharmacology

Background:

• Essential and renal hypertension often require complex treatment regimens.
• Previous therapies including diuretics, beta-blockers, and other antihypertensives may be insufficient for some patients.

Purpose of the Study:

• To evaluate the efficacy and tolerability of nitrendipine as an add-on therapy for patients with essential or renal hypertension.
• To assess nitrendipine's role in combination treatment for difficult-to-stabilize hypertension.

Main Methods:

• An open-label study included 55 patients with inadequately treated hypertension.
• Patients received nitrendipine (20-40 mg twice daily) in addition to their existing diuretic and beta-blocker therapy, potentially combined with other agents like reserpine or clonidine.
• Treatment duration varied, with 18 patients followed for over a year.

Main Results:

• Blood pressure normalization was achieved in 46 out of 55 patients (83.6%).
• Long-term efficacy was demonstrated, with 18 patients treated successfully for over one year.
• Nitrendipine exhibited a favorable side effect profile, with only minor adverse events reported (dizziness, ankle edema, rash in one case).

Conclusions:

• Nitrendipine is a well-tolerated and effective agent for combination therapy in patients with essential or renal hypertension.
• It proves particularly useful for managing hypertension that is difficult to stabilize with conventional treatments.
• The addition of nitrendipine offers a valuable therapeutic option to improve blood pressure control.
